HS v2022 Code: 291733

About acids; aromatic polycarboxylic acids; dinonyl or didecyl orthophthalates

HS code 291733 covers a range of aromatic polycarboxylic acids, including dinonyl or didecyl orthophthalates. These chemicals play a crucial role in various industries, serving as important intermediates and building blocks for the production of a wide array of products. The global demand for these aromatic polycarboxylic acids continues to grow, driven by their diverse applications in plastics, coatings, adhesives, and other industrial sectors, making this code an integral part of the broader chemical industry.

Production process

The production of the chemicals covered under HS code 291733 typically involves a multi-step process. The starting point is the oxidation of aromatic hydrocarbons, such as xylene or naphthalene, to obtain the desired polycarboxylic acids. This is often followed by esterification reactions to produce the dinonyl or didecyl orthophthalates. The specific production techniques may vary depending on the target product, but generally involve the use of catalysts, controlled temperature and pressure conditions, and careful purification steps to ensure the desired purity and quality of the final products.

Production inputs

The main inputs required for the production of the chemicals under HS code 291733 include aromatic hydrocarbons, such as xylene or naphthalene, as well as various alcohols, such as nonyl alcohol or decyl alcohol, for the esterification process. Additionally, the production may require specialized equipment, such as reactors, distillation columns, and purification systems, as well as a range of catalysts and other chemical reagents. The availability and cost of these raw materials and production resources can significantly impact the overall competitiveness of this industry.

Production outputs

The chemicals covered under HS code 291733 are primarily used as intermediates in the production of a wide range of downstream products. The aromatic polycarboxylic acids, such as phthalic acid, can be used in the manufacture of 391690 Plastics and articles thereof, n.e.s., 320910 (Paints and varnishes (including enamels and lacquers), based on synthetic polymers or chemically modified natural polymers, dispersed or dissolved in a non-aqueous medium), and 390791 Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms. The dinonyl or didecyl orthophthalates are commonly used as plasticizers in the production of 391810 Floor coverings of plastics, whether or not self-adhesive, in rolls or in the form of tiles and 392010 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
